Real-time Multi-perspective Rendering on Graphics Hardware
(The Eurographics Association, 2006)Multi-perspective rendering has a variety of applications; examples include lens refraction, curved mirror re- flection, caustics, as well depiction and visualization. However, multi-perspective rendering is not yet practical ... -
Real-time Soft Shadow Mapping by Backprojection
(The Eurographics Association, 2006)We present a new real-time soft shadow algorithm using a single shadow map per light source. Therefore, our algorithm is well suited to render both complex and dynamic scenes, and it handles all rasterizable geometries. ... -
Reconstruction of Volumetric Surface Textures for Real-Time Rendering
(The Eurographics Association, 2006)Volumetric texturing is a popular technique for rendering rich 3-D detail when a polygonal surface representation would be ineffective. Although efficient algorithms for rendering volumetric textures have been known for ... -
Relighting Human Locomotion with Flowed Reflectance Fields
(The Eurographics Association, 2006)We present an image-based approach for capturing the appearance of a walking or running person so they can be rendered realistically under variable viewpoint and illumination. In our approach, a person walks on a treadmill ... -
Segmentation-Based 3D Artistic Rendering
(The Eurographics Association, 2006)This paper introduces segmentation-based 3D non-photorealistic rendering, in which 3D scenes are rendered as a collection of 2D image segments. Segments abstract out unnecessary detail and provide a basis for defining new ... -
Sequential Sampling for Dynamic Environment Map Illumination
(The Eurographics Association, 2006)Sampling complex illumination in the form of environment maps has received a lot of attention in computer graphics. Recent work in this area has demonstrated that drawing samples from the product of light and BRDF produces ... -
Silhouette Texture
(The Eurographics Association, 2006)Using coarse meshes with textures and/or normal maps to represent detailed meshes often results in poor visual quality along silhouettes. To tackle this problem, we introduce silhouette texture, a new data structure for ... -
Sparse Lumigraph Relighting by Illumination and Reflectance Estimation from Multi-View Images
(The Eurographics Association, 2006)We present a novel relighting approach that does not assume that the illumination is known or controllable. Instead, we estimate the illumination and texture from given multi-view images captured under a single illumination ... -
Spatio-Angular Resolution Tradeoffs in Integral Photography
(The Eurographics Association, 2006)An integral camera samples the 4D light field of a scene within a single photograph. This paper explores the fundamental tradeoff between spatial resolution and angular resolution that is inherent to integral photography. ... -
A Spectral BSSRDF for Shading Human Skin
(The Eurographics Association, 2006)We present a novel spectral shading model for human skin. Our model accounts for both subsurface and surface scattering, and uses only four parameters to simulate the interaction of light with human skin. The four parameters ... -
Statistical Acquisition of Texture Appearance
(The Eurographics Association, 2006)We propose a simple method to acquire and reconstruct material appearance with sparsely sampled data. Our technique renders elaborate view- and light-dependent effects and faithfully reproduces materials such as fabrics ... -
Surface Enhancement Using Real-time Photometric Stereo and Reflectance Transformation
(The Eurographics Association, 2006)Photometric stereo recovers per-pixel estimates of surface orientation from images of a surface under varying lighting conditions. Transforming reflectance based on recovered normal directions is useful for enhancing the ... -
Symmetric Photography: Exploiting Data-sparseness in Reflectance Fields
(The Eurographics Association, 2006)We present a novel technique called symmetric photography to capture real world reflectance fields. The technique models the 8D reflectance field as a transport matrix between the 4D incident light field and the 4D exitant ... -
Texture Replacement of Garments in Monocular Video
(The Eurographics Association, 2006)In this paper, we present a video processing algorithm for texture replacement of moving garments in monocular video recordings. We use a color-coded pattern which encodes texture coordinates within a local neighborhood ... -
Texture Transfer Using Geometry Correlation
(The Eurographics Association, 2006)Texture variation on real-world objects often correlates with underlying geometric characteristics and creates a visually rich appearance. We present a technique to transfer such geometry-dependent texture variation from ... -
Tomographic Reconstruction of Transparent Objects
(The Eurographics Association, 2006)The scanning of 3D geometry has become a popular way of capturing the shape of real-world objects. Transparent objects, however, pose problems for traditional scanning methods. We present a visible light tomographic ... -
Two Stage Importance Sampling for Direct Lighting
(The Eurographics Association, 2006)We describe an importance sampling method to generate samples based on the product of a BRDF and an environment map or large light source. The method works by creating a hierarchical partition of the light source based on ... -
Visual Chatter in the Real World
(The Eurographics Association, 2006)When a scene is lit by a source of light, the radiance of each point in the scene can be viewed as having two components, namely, direct and global. Recently, an efFIcient separation method has been proposed that uses high ... -
Warping and Partitioning for Low Error Shadow Maps
(The Eurographics Association, 2006)We evaluate several shadow map algorithms based on warping and partitioning using the maximum perspective aliasing error over the entire view frustum. With respect to our error metric, we show that a range of warping ... -
Wavelet Radiance Transport for Interactive Indirect Lighting
(The Eurographics Association, 2006)Global illumination is a complex all-frequency phenomenon including subtle effects caused by indirect lighting. Computing global illumination interactively for dynamic lighting conditions has many potential applications, ...
